Going back to kernel 3.16.0-30-generic fixes the problems for now. Given
from the RedHat bug report the problem seems to be present in 3.17
kernel as well. It seems some change between 3.16 and 3.17 caused this
as a regression.

Title:
  touchpad does not respond to tap-to-clicks in I2C mode in Ubuntu 15.04
  on 2015 XPS 13 (9343)

Status in Dell Sputnik:
  Confirmed
Status in linux package in Ubuntu:
  Incomplete
Status in xserver-xorg-input-synaptics package in Ubuntu:
  New
Status in xserver-xorg-input-synaptics package in Fedora:

Bug description:
  Tap-to-click does not work unless I tap several times really fast
  (which is really hard to do), which also causes the cursor to move.
  This is a poor user experience.

  Relatedly, sometimes when using two-finger scrolling, the touchpad
  will get stuck such that I can let go and the cursor won't move. I can
  continue using two fingers to try scrolling, which works, but I can't
  get the cursor to move. If I tap the cursor several times really fast,
  I can eventually get the cursor unstuck so it moves again. I suspect
  that this is related to the tap-to-click issue.
